Scintillating glass optical fibers are the first viable medium for large-area, solid-state, thermal neutron sensors that have applications in national security, medicine, and materials research. Here, ultraviolet-induced fluorescence mimics scintillation.

The photographs in my set, "Weed Flower Micros," may appear to be close-ups of regular-sized flowers – they are not!
These are micro (macro) photos of tiny little flowers which bloom on ordinary weeds found in my lawn.
How tiny? The largest weed flower in the set is only, when measured across its widest part from petal tip to petal tip, 3/4" in diameter (19mm)!
Some of these miniscule flowers are so small that the entire blossom you are looking at is 1/4" in diameter (6mm)…or smaller! Again, that’s measuring from petal tip to petal tip across the widest part of the bloom!
The smallest part of a weed flower that I have managed to successfully shoot and achieve good detail in is a photo I made of a bud that measured LESS than 1/32" in diameter (0.7mm) across its widest part!
For size references I have included a photo of certain flowers and buds next to the head of an ordinary paper match, which dwarfs the blooms and buds.
It’s delightful to discover the beauty, complexity, and variety in something so small that it’s easily ignored, taken for granted, dismissed as a pest, or just downright difficult to see with the naked eye.
And it’s an even greater delight to realize that this incredible beauty has been growing wild in my lawn, year after year, right under my un-seeing eyes as I’ve repeatedly mown them down with my lawn mower, never realizing the unseen beauty that I was trampling under my feet.
I hope you enjoy viewing these as much as I do. I have a lot of fun making them for us to look at!

This is a 5 megapixel image sensor from my old HTC Aria Smart Phone.
This is a little bigger than 1:1 macro since the Nikkor 40mm 2.8G DX can be manually focused a little past 1:1. I used both of my SB-700's for this. They were set to 1/50th power.

inspired by rising buzz about micro four thirds, which is just what i was missing so long. it was made first for myself, as long, as other charts, just to make an system in all absorbed information. maybe someone of you will find it useful.

During summer aircraft take off on an almost daily basis. Concordia is a hubbub of activity as researchers from disciplines as diverse as astronomy, seismology, human physiology and glaciology descend to work in this unique location.
For the rest of the year, around 14 crewmembers remain to keep the station running during the cold, dark winter months.
ESA sponsors a research medical doctor in Concordia to study the effects of living in isolation. The extreme cold, sensory deprivation and remoteness make living in Concordia similar to living on another planet.

My god, first off I really need to clean my sensor. This is the reason why I rarely shoot wide open, the moment I stop down all that dust thats in there that I don't bother to clean just shows right up. Thankfully dust isn't really an issue when you normally live at the widest apertures, but there are those few times where I want everything sharp and in focus, and those moments are few and far between. Think on average I stop down for a photo less than once a week. Well also got to say to me the Zeiss Ikon is the best rangefinder I've ever used and I've used many. To me a couple of its biggest draws come form the fact that it has the brightest viewfinder on any rangefinder I've ever used. Much brighter than any Leica thats for sure. It also has aperture priority which is a big plus in my books, and a 1/2000 max shutter speed which is also a plus for me since I like to shoot wide open. Plus unlike a Leica it has the hinged back so its easier to load the film and not some convoluted way like the Leica does. It also has that little film window in the back which is useful to me as I will often forget what I'm shooting. Plus a whole bunch of other small things that just make me love this camera. Point is I don't plan on ever getting rid of this but who knows maybe when I'm living on the streets I might have to but for now I rather keep it for as long as possible.
Alright so about the photo, this took quite some time to set up and shoot mainly because I used all 5 of my lights for this photo. Also no matter how much I cleaned the tile the Zeiss was sitting on there was dust not matter what. Dust everything! On the camera, on the tile, in my sensor it was just terrible cleaning this up in post. I didn't even bother getting all of it either I gave up after sitting here and cleaning for 30+ minutes. So I missed quite a bit of spots but whatever. So interesting part about this photo is that its also a composite. I used my DIY ring flash for this photo but I shoot it as close to the Zeiss Ikon as I could in order to get a large catchlight in the lens, which meant it was in the frame. So I combined the photos with the ring flash and without it. I also took another flash exposure where I bounced a flash into a white piece of foam core just above the camera (and my a850) in order to get a glared up viewfinder, frame line illumination window, and rangefinder window. I just composited those elements together and this is what I got. Not bad, could use a little more cleaning up by I think its a pretty cool shot, especially because of the glow I get from chrome finish.
Storbist Info
2x Nikon SB-800 + 2x Nikon SB-28 all bare, at the top, bottom, left and right of the frame on the ground all firing at 1/8th power. Also the tile was about 1-2" off the ground that way these flashes would just light the top half of the camera and not cause any shadows.
Nikon SB-80DX directly above the Zeiss Ikon with a DIY ring flash firing at full power (flash composite as the ring flash was in the frame in order for it to be as close to the subject as possible)
Nikon SB-80DX directly above the frame firing into 2 20x30 sheets of white foam core above the set at full power (another flash composite, used in order to glare up the windows in the rangefinder)
PNNL’s improved Sensor Fish is a small tubular device filled with sensors that analyze the physical stresses fish experience as they pass through dams and other hydropower structures. The device’s latest version costs about 80 percent less and can be used in more hydro structures than its predecessor, according to a paper published in the journal Review of Scientific Instruments.
